する過荷重防止装置。[Claims for Utility Model Registration] An overload prevention device for preventing overturning of the working vehicle by regulating the operation of the boom in a working vehicle equipped with a boom that can be freely extended, retracted, raised and rotated, comprising: a computing unit that calculates a moment that acts in a direction to overturn the work vehicle in response to the operation of the boom; an operation regulating means that regulates the operation of the boom; a regulation release operation means that sends a regulation release signal; and a controller that controls the operation of the means, and this controller is configured to control when the moment reaches a first allowable operation range limit set corresponding to the operation of the boom, if the restriction release signal is not input. When the actuation restriction means is actuated and the restriction release signal is input, the actuation restriction is activated when the moment reaches a second allowable actuation range limit set outside the first allowable actuation range limit. An overload prevention device characterized in that it is configured to actuate a means.
